Definitions

  • This invention relates to terminals for making electrical connection to an electrical conductor, e.g., a wire.
  • the wire can be securely connected by pushing a free end of the wire into the terminal.
  • the free end is held between a metal supporting base and a springy metal gripper that has a burred edge to grab the wire, preventing it from being withdrawn.
  • the gripper is oriented at such an angle to the base that when the wire is inserted it forces an opening between the gripper and the base.
  • the gripper and the base are permanently assembled by stitching or crimping, or are formed from a single piece, or are held in proper orientation by a plastic housing.
  • U.S. Pat. No. 4,087,149 shows a terminal in which the base is a conventional flat plug tang of the kind used with electrical appliances; and the gripper is bow-shaped and has one long limb that rests along one side of the tang and a shorter gripping finger that has the burred edge. The wire is held between the tang and the finger.
  • the long limb has a nipple that sits in a hole in the tang to prevent the gripper from sliding off the base.
  • One general feature of the invention is a terminal that has a base and a gripper that is held in a fixed position along the length of the base by having the gripping finger act in tension in one direction at a first location along the length of the base and having a back portion of the gripper act in the opposite direction at a second location spaced apart along the length of the base from the first location to resist the tension.
  • the base has a projection at the first location and an end of the base is at the second location.
  • the base is sheet metal and the projection is a flap bent away from the metal sheet.
  • the base includes a trough for seating the free end of the conductor, and a shoulder adjacent to the trough bears the projection.
  • the gripper also has a supporting leg (connected to the back portion) that contacts the base on the opposite side from the side on which the conductor is pressed into contact with the base.
  • the terminal is adapted to make contact to a plurality of conductors and there are a plurality of gripping fingers (defined by parallel slits in the gripper) for respective conductors.
  • the base has a trough, shallower than the thickness of the conductor, for seating each conductor.
  • the back portion has a hole colinear with the trough to receive the conductor.
  • the gripping finger has a burred edge which presses against the conductor.
  • the gripping finger is oriented at an acute angle to the supporting leg (e.g., 45° when the conductor is not being held in the terminal).
  • the base and the gripper cooperate to form a self-supporting assembly.
  • the conductor is 12-gauge wire.
  • the base is a high-copper-content brass alloy and the gripper is stainless steel.
  • the terminal is housed in an insulative housing.
  • the base also includes a male prong or a female receptacle that mates with a prong or receptable of another terminal.
  • the terminal is part of a male or female connector which is part of a modular cable.
  • the gripper fits over one end of the terminal and holds one conductor, and a second gripper fits over another terminal to hold another conductor.
  • the base includes metal surface that makes electrical contact with the conductor.
  • Another general feature of the invention is a terminal in which the supporting leg of the gripper makes contact with the base only at locations that are not as near to the end of the conductor as the locations at which the gripping finger presses the conductor.
  • the supporting leg has a flat portion that lies along the base beginning at the end opposite the end of the conductor; and the gripping finger presses the conductor at a single location.
  • Another general feature of the invention is a terminal in which the pressing of the conductor into contact with the base is accomplished only by resilience of the gripping finger along a section that does not extend beyond the end of the base.
  • Another general feature of the invention is a terminal in which the base has a plurality of troughs of different dimensions for respectively seating wires of different gauges.
  • Another general feature of the invention is a method for assembling a self-supporting terminal in which the base is inserted in an opening defined by the free ends of the supporting leg and gripping finger to a position in which the free end of the gripper contacts the base at a pivot point, and the gripper is rotated about the pivot point until the back portion contacts the end of the base and the free end of the gripper engages a projection on the base.
  • the terminal of the invention is easily, simply, and economically fabricated and is self-supporting without requiring welding, stitching, or crimping.
  • the terminal will retain the wire even though the material of the insulative housing may flow.
  • the base can be easily and simply fabricated of high-conductivity material to provide an excellent electrical connection.
  • the gripper can be easily and simply fabricated from heat-treatable stainless steel. Many wires of different gauge can be accommodated in a single terminal. Limiting the spring moment to a short section of the gripper and keeping the gripping finger at an angle of 45° to the supporting leg assures a secure connection.
  • the troughs assure good contact and permit relatively easy insertion of the conductor.
  • the burred edge assures a tight grip.
  • the terminal can be part of an inexpensively fabricated modular cable or can be used to interconnect a number of individual wires.
  • FIG. 1 is an isometric view of an electrical terminal holding a wire.
  • FIG. 2 is an exploded view of the terminal of FIG. 1.
  • FIG. 3 is a side-sectional view at 3--3 of FIG. 1.
  • FIGS. 4 and 5 are top and side views of the terminal of FIG. 1 nestled in a representative section of a plastic housing.
  • FIG. 6 is an isometric exploded view of male and female terminal housings.
  • FIG. 7 is an isometric view of mated housings with cables.
  • FIG. 8 is a diagram of a power distribution system.
  • FIGS. 9, 10 illustrate assembly of the terminal.
  • FIG. 11 is a side view of an alternate embodiment.
  • a self-supporting electrical terminal 10 includes a stamped metal base 12 and a formed steel gripper 14 that together securely hold and make electrical connection to the free uninsulated end of a 12-gauge insulated copper wire 16.
  • Base 12 is made of a brass alloy with very high copper content (Olin 194).
  • Gripper 14 is made of high carbon content 420 stainless steel.
  • base 12 includes three troughs 18, 20, 22, for seating three separate wires.
  • Troughs 18 and 22 are sized to snugly seat 12-gauge wires; trough 20 is smaller and is sized to snugly seat an 18-gauge wire.
  • Troughs 18 and 20 and troughs 20 and 22 are respectively separated by shoulders 24, 26. On each shoulder 24, 26 is a flap 28, 30.
  • Each trough is about 1/2" long and is shaped to assure contact with a substantial area of the surface of wire 16.
  • Gripper 14 is bent to form a supporting leg 32, a set of resilient gripping fingers 34, 36, 38, and a back portion 40 joining the supporting leg to the gripping fingers.
  • Gripping fingers 34, 36, 38 are defined by parallel slits 42, 44. Fingers 34, 38 are slightly wider than finger 36. When assembled, fingers 34, 36, 38 respectively cooperate with troughs 18, 20, 22 (as shown in FIG. 1).
  • the back portion 40 of gripper 14 has three openings 46, 48, 50 that can receive three wires (12-gauge wires in the case of openings 46, 50; 18-gauge wire in the case of opening 48). Fingers 34, 36, 38 have a burred edge 52 for biting into the surface of each wire.
  • finger 36 when assembled, finger 36 is in tension against flaps 28, 30 and the back portion 40 is in contact at point 60 with the end of base 12 that is opposite the end 62 of wire 16, thus resisting the tension in finger 36.
  • the supporting leg 32 is in contact with the bottom of base 12.
  • the burred edge 52 bites into wire 16 to prevent it from being removed from the terminal (except by simultaneous twisting and pulling of the wire).
  • Back portion 40 is perpendicular to supporting leg 32 and gripping fingers 34, 36, 38 are at 45° (angle b) to the back portion.
  • gripper 14 When assembled, gripper 14 is slightly skewed relative to base 12 so that the angle (a) between back portion 40 and base 12 is slightly offset form 90° and the angle between each gripping finger and the base is slightly offset from 45°.
  • Finger 34 makes contact with base 12 at a point that is nearer to end 62 of wire 16 than the point at which supporting leg 32 makes contact with base 12.
  • the pressure applied by fingers 34, 36, 38 is based on the resilience of those fingers and not on any resilience of back portion 40, or supporting leg 32.
  • the relative short length of the resilient fingers and the configuration of the supporting leg and back portion helps to provide a strong pressure on base 12 and wires 16, assuring a tight connection.
  • Base 12 also includes a female receptacle 64 arranged to mate with a male prong (not shown in FIG. 3) of another terminal that is similar to terminal 10 except for the substitution of the prong for the receptacle.
  • terminal 10 is nestled within a chamber 68 in an insulative plastic housing 70. Although terminal 10 fits relatively snugly within chamber 68, terminal 10 does not require support from the walls of the chamber and remains self-supporting even if the housing 70 is distorted by heat flow.
  • a tab 7 within chamber 68 helps to guide wire 16 into its trough during insertion.
  • a hole 74 is provided colinear with each corresponding trough to receive each wire.
  • housing 70 has two mating sections 82, 84 which, when assembled, define chamber 68 and four other similar chambers in a row, each chamber being arranged to hold a terminal like terminal 10.
  • Female housing 70 mates with a male housing 86 that also has two mating sections 88, 90 that similarly define chambers for holding terminals that are the male counterparts of the terminals held in housing 70.
  • housing 70 and housing 86 form mating male and female connectors that can be used to interconnect 12-gauge wires of one cable 90 and a second cable 92. Simultaneously, 18-gauge wires 94 can also be inserted into connector 70 to make connection to cable 90.
  • each cable 90, 92 can also have a second connector (of the opposite sex) attached to its other end to form modular cables that can be interconnected with other modular cables to distribute power from a source 100 to power using appliances 102 (e.g., fluorescent fixtures).
  • appliances 102 e.g., fluorescent fixtures
  • base 12 is inserted into the opening defined in gripper 14 between the gripping fingers and supporting leg to a position such that a free edge 106 of supporting leg is in contact with the bottom of base 12. Then the gripper is rotated into position such that finger 36 is in tension against flap 28 and back portion 40 touches the end 60 of base 12, resisting the tension in the finger. This produces a self-supporting assembly in which gripper 14 cannot move in either direction along base 12.
  • each terminal is nestled into a chamber in one half of the plastic housing and the other half is placed over the terminals to form a connector. Finally, wires are inserted into appropriate ones of the terminals.
  • the terminal of the invention is easily, simply, and economically fabricated and is self-supporting without reguiring welding, stitching, or crimping.
  • the terminal will retain the wire even though the material of the insulative housing may flow.
  • the base can be easily and simply fabricated of high-conductivity material to provide an excellent electrical connection.
  • the gripper can be easily and simply fabricated from heat-treatable stainless steel. Many wires of different gauge can be accommodated in a single terminal. Limiting the spring moment to a short section of the gripper and keeping the gripping finger at an angle of 45° to the supporting leg assures a secure connection.
  • the troughs assure good contact and permit relatively easy insertion of the conductor.
  • the barred edge assures a tight grip.
  • the terminal can be part of an inexpensively fabricated modular cable or can be used to interconnect a number of individual wires.
  • base 12 can be extended to include a second set of troughs 120 that are identical to the original troughs but open in the opposite direction.
  • a second gripper 122 identical to gripper 14 can be attached over troughs 120 to permit wires (e.g., wire 124) to be electrically connected to wire 16.
